The next version of Maxima will use gnuplot for plotting. The first beta
release is available now from <http://maxima.sf.net>;. In the new version
you will get the output you want from
plot2d(abs(1/(1+x*%i)),[x,0,10],[gnuplot_preamble,"set logscale y"]);
It isn't the prettiest interface, but it does work.
